ID of pygmy pipefish?, Arrow crab? and two shrimps

Sorry for the double posting.I spotted this tiny (2-3? cm) pipefish on a day dive in a bit of current in Lembeh, Indonesia.http://www.flickr.co...157632194977305A friend thinks it's Pygmy Pipedragon [Kyonemichthys rumengani], but I don't think so. I checked poppe-images.com (despite it being for Philippines) since it had quite a few pipefish, but no luck :/

The second one (fairly big so maybe 5-8? cm incl. the legs (from Malapascua, Philippines)) I'm trying to ID someone called an Arrow crab, but shouldn't he have a longer chainsaw-like snout to be an arrow crab or can they be without them?http://www.flickr.co...157632183080671

Nice shots! I like the arrow crab a lot. I don't have an ID for these, but I do want to offer a tip - its easier for everyone if you include the photos in your post. Just click "Share" from Flickr, click "Grab the HTML/BBCode", click BBCode, copy and paste:
